Firefox will not open ... no matter what I do
In the last few weeks Firefox will not open even when using admin rights. NOTE: I have followed all available posts including multiple uninstalls (complete), deleting Firefox folders, reinstalling, etc. There have been no major (or known) changes to my Windows 10 Pro system. I run Heimdal Thor and Kaspersky antivirus protection and there have been no conflicts running both at any time. I also use Acronis Protection (I know it may seem like overkill but it works). I have turned off each of the above and Firefox still does not open. Firefox runs with no problems on my personal and work laptops. I am CompTia A+ Certified so somewhat knowledgeable (a little knowledge is a dangerous thing!) and have run sfc /scannow with no issues noted. Plus, two Heimdal support reps have logged onto my system, attempted to find a solution, found no issues with my system (Omen 880 even though I don't game). My wife is a dedicated Firefox user and wants it back.

Found the solution (and there were other programs that would not open!): I have CCleaner Pro. One option is to "Performance Optimizer" that puts programs to sleep. I had done some some time ago and at that point I could not open: Firefox, Dymo LabelWriter, Heimdal, Nvidia GeForce Experience, and the list goes on. Having tried everything under the sun (including the "nightly Firefox version" that would run) and still finding myself frustration that needed programs would not open (and had turned off all of my antivirus/protection programs), I did an experiment and "woke up" Firefox. Viola! It ran! Now have awakened all programs and all are running. I plan to notify CClearner as well as other support groups that spent hours attempting to help.
Appreciate the help here.

Why not try this, this is the nightly version of firefox, somewhat different from the stable version, but fix itself every night. https://download.mozilla.org/?product=firefox-nightly-latest-ssl&os=win64&lang=en-US&_gl=1*7jkim8*_ga*NjE5MzY2Njc0LjE2MzM5NjQwODQ.*_ga_MQ7767QQQW*MTY1NTQ3NTA0Ny41LjAuMTY1NTQ3NTA0Ny4w
Wow! Thank you so much! Up and running.
